If you’re using an iPhone to take pictures and videos, you may have noticed that the camera sometimes struggles to focus. This is because the camera has a built-in autofocus system that tries to keep track of where your subject is in the frame, and if it can’t find them, it will try to focus on other things. But if you want to stop the autofocus from working altogether, there are a few steps you can take. First, open up the Camera app and select “Settings.” Then, under “Autofocus,” make sure “Disable autofocus.” Finally, press “OK” to save your changes.
